Motor speed in non-inverter type refrigerator/AC remains constant and temperature is adjusted by turning the motor ON and OFF, which consumes more energy. In inverter type refrigerator/AC, temperature is adjusted by changing motor speed without turning the motor ON and OFF. Compared to non-inverter type, refrigerator/AC with inverters have less power loss and can save in energy.
